WebInterestingly, when both reactants have one electron-rich or one electron-poor group, the reaction favors the meta product. Meta, in this context, means the groups locate two carbons away from one another. Similarly electron-rich groups between the dienophile and diene result in a meta product. http://iverson.cm.utexas.edu/courses/310N/MainPagesSp06/NucleophilesElectrophiles.html WebApr 10, 2024 · “I am honored to take on the role of laboratory director at Brookhaven, a truly exceptional national laboratory with a rich history and a talented and dedicated staff,” said Hewett. “The Lab has an extremely bright future, one that will help solve some of the greatest scientific challenges facing the world today.” kids room with wall shelves
